- A major hotel chain is constructing a new resort hotel complex in Greenbranch Springs, WestVirginia. The resort is in a heavily wooded area, and the developers want to preserve as much ofthe natural beauty as possible. To do so, the developers want to connect all the various facilitiesin the complex with a combination walking–riding path that will minimize the amount of pathwaythat will have to be cut through the woods. The following network shows possible connectingpaths and corresponding distances (in yards) between the facilities: Determine the path that will connect all the facilities with the minimum amount of constructionand indicate the total length of the pathway.arrow_forwardThe manager of the customer service department at a bank can hire employees with a high school degree (HS) who earn $10,000 annually or employees with a bachelor's degree (B) who earn $20,000.

A treatment group of 18 repairpersons was assigned to a dispatcher who monitored all the incoming requests for cable repairs and then provided a service strategy for that day’s work orders. A control group of 18 repairpersons was to perform their work in a normal fashion—that is, by providing service in roughly a sequential order as requests for repairs were received. The average daily mileages for the 36 repairpersons are recorded in the table below.  What are the populations of interest in this study?  What is the level of significance of your test?  Is there significant evidence that the treatment group had a smaller average daily mileage than the control group?
